Best Answer: You're wrong about what the arctan function is. arctan is that function that answers the question, What angle theta yields the tan (theta) = x? arctan 0 = 0 because the tan 0 = sin 0 / cos 0 = 0/1 = 0.
Tangent of arctangent: tan( arctan x) = x: Arctan of negative argument: arctan(-x) = - arctan x: Arctan sum: arctan Î± + arctan Î² = arctan [(Î±+Î²) / (1-Î±Î²)] Arctan difference: arctan Î± - arctan Î² = arctan [(Î±-Î²) / (1+Î±Î²)] Sine of arctangent: Cosine of arctangent: Reciprocal argument: Arctan from arcsin: Derivative of arctan
